RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 11/413,922, entitled, “Providing Guest Users Access to Network Resources Through an Enterprise Network,” by Hassan et al, filed Apr. 28, 2006, the entire contents of which is hereby incorporated by reference.

BACKGROUND

In today's world, enterprises often serve as hosts to visitors, for example, vendors, partners, clients, members, colleagues, students, etc., for any of a variety of purposes. These guests often desire to access the Internet or another network (e.g., the networks of their own enterprises) using their mobile user devices, such as, for example, laptop computers, notebook computers, telephones, Blackberry™ brand devices, PCS devices, personal digital assistance (PDAs), etc. Thus, host enterprises often provide guests access to network resources through the host enterprise's network. As used herein, enterprises include, but are not limited to: companies; corporations; partnerships; sole proprietorships, other types of business entities; organizations; non-profit organizations; governmental bodies and/or agencies; educational institutions; other types of enterprises; and any suitable combination of the foregoing.

Providing guests access to network resources (e.g., a portion of the host network, the Internet, a guest enterprise network, etc.) often requires the use of dedicated hardware and/or software, and the installment and the maintenance of same. These dedicated solutions are not simple. Most require information technology (IT) support and/or the assistance of one or more administrators or receptionists. Thus, in order to provide guests with access to network resources, host enterprises typically incur the costs of dedicated hardware and/or software, IT support, and/or administrative assistance.

SUMMARY

This Summary provides an illustrative context for aspects of the invention, in a simplified form. It is not intended to be used to determine the scope of the claimed subject matter. Aspects of the invention are described more fully below in the Detailed Description.

Described herein are systems and methods enabling guests to access network resources through an enterprise network using a guest user account. A guest user account may be created for a guest for a limited time (a day, a couple days, certain times during certain days (e.g., 9:00 a.m. to 5:00 p.m.), a week, or even longer). Guest account credentials (e.g., a guest account ID and password) of the guest account may be provided to the guest, which allow the guest to use the guest account. Any of a variety of techniques, including those described herein, may be used to provide the guest account credentials to the user. Providing the credentials may involve obtaining information from the guest user, and providing guest access credentials in response to obtaining the information. Obtaining the information about the guest user may include scanning a guest access card, credit card or mobile telephone of the guest user, receiving an email or letter, or orally in person or by telephone. A guest access management server may be configured to generate and maintain guest accounts, authenticate guest users, and track and log guest activity.

In some embodiments, virtual LAN (i.e., VLAN) technology may be used to separate guest traffic from host enterprise traffic on the host enterprise network. By using VLAN technology, the host enterprise's existing network infrastructure may be used, as opposed to having to modify the infrastructure. After a guest user is authenticated, communications to and from the guest user may be routed to a guest VLAN. Within the guest VLAN, the user may be allowed to access network resources such as the Internet or the guest enterprise's network.

In an embodiment of the invention, a guest user to enabled to access network resources through an enterprise network. Information read from an object (e.g., a credit card, a guest access card, a mobile telephone, etc.) in the possession of the guest user is received. One or more guest account credentials for accessing the network resources through the enterprise network are determined based on the read information, and the one or more guest account credentials are indicated to the guest user.

In another embodiment, a system is provided for enabling a guest user to access network resources through an enterprise network. The system includes a guest access management server to determine, based on the information read from an object (e.g., a credit card, a guest access card, a mobile telephone, etc.) in the possession of the guest user, one or more guest account credentials for accessing the network resources through the enterprise network, and to initiate an indicating of the one or more guest account credentials to the guest user.

In yet another embodiment, a computer program product is provided, which includes a computer-readable medium and computer-readable signals stored on the computer-readable medium. The signals define instructions that, as a result of being executed by a computer, control the computer to perform a method of a method of enabling a guest user to access network resources through an enterprise network. The method includes acts of: (a) receiving information read from a guest access card of the guest user; (b) determining, based on the read information, one or more guest account credentials for accessing the network resources through the enterprise network; and (c) indicating the one or more guest account credentials to the guest user.

In another embodiment, a guest user is enabled to access network resources through an enterprise network. Information from a credit card vendor verifying an identity of the guest user is received. One or more guest account credentials for accessing the network resources through the enterprise network are determined based on the received information, and the one or more guest account credentials are indicated to the guest user.

In another embodiment, a system is provided for enabling a guest user access to network resources through an enterprise network. The system includes a guest access management server to receive information from a credit card vendor verifying an identity of the guest user, to determine, based on the received information, one or more guest account credentials for accessing the network resources through the enterprise network, and to initiate an indication of the one or more guest account credentials to the guest user.

In yet another embodiment, a user is enabled to access network resources through an enterprise network. At a server of a credit card vendor, information read from a credit card of the user by a credit card scanner on premises of the enterprise is received.

DETAILED DESCRIPTION

Although embodiments of the invention are described below in relation to providing guest users wireless access to network resources through a host enterprise network, the invention is not so limited, but rather, may be implemented for non-wireless (e.g., wireline) access.

The function and advantage of the above embodiments and other embodiments of the present invention will be more fully understood from the examples described below. The following examples are intended to facilitate a better understanding and illustrate the benefits of the present invention, but do not exemplify the full scope of the invention.

As used herein, whether in the written description or the claims, the terms “comprising”, “including”, “carrying”, “having”, “containing”, “involving”, and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of”, respectively, shall be closed or semi-closed transitional phrases, as set forth, with respect to claims, in the United States Patent Office Manual of Patent Examining Procedures (Eighth Edition, Revision 2, May 2004), Section 2111.03.

EXAMPLES

In some embodiments, a guest user is granted guest access through a host enterprise using a guest access card issued by the host enterprise. Prior to, or at the time of, the guest's arrival at the host enterprise, the guest may be provided a guest access card. The guest access card may encode (in clear text or encrypted form) guest account credentials for a guest account, such as, for example, a guest access ID and password, or may encode a value that is associated with a guest account and/or guest account credentials. Guest account credentials and/or other information may be stored on a magnetic strip or in semiconductor memory on the guest access card.

Upon arrival at the host enterprise (e.g., a lobby or reception area), the guest user may attempt to access network resources (e.g., the Internet and/or the guest's corporate network) using a user device (e.g., a laptop or PDA) and may be prompted for guest account credentials (e.g., a guest account ID and password). Prior to, during or after attempting to access network resources, the guest user may scan the guest access card (e.g., magnetically, optically or using RF technology) using a scanner on the host enterprise's premises (e.g., in a reception area or lobby), which may be specifically designed for this purpose. A guest access management server on the host network may receive the scanned information and determine guest account credentials. This determination may be made simply by reading the guest account credentials provided by the guest access card, by decrypting encrypted account information on the card or by mapping information provided by the card to a guest account ID and password. The guest account credentials may be sent to a device capable of indicating them to the guest user, for example, a device in the vicinity of the guest user and/or scanner. Such a device may be or include any of the following: a display device (e.g., a monitor); a printer; a device that produces badges and/or ID cards, a speaker; a telephone; another type of device; or any suitable combination of the foregoing.

The guest user then may log into the host enterprise network using the guest credentials, for example, using a user device (e.g., a laptop or PDA). The host enterprise network may be configured to limit guest user access, for example, to the Internet and/or the guest's enterprise network. For example, the host enterprise network may employ virtual local area network (VLAN) technologies to limit the guest's access based on the guest access account of the guest user. The host enterprise network then may monitor the network activity of the guest and, if necessary, bill the guest user for access to particular network resources such as, for example, the Internet.

Further, the guest account may be configured to have a limited duration such as, for example, a certain (e.g., predefined) number of hours, days, weeks, months, or a combination thereof. The guest account may further be configured for use only during specific times within the limited duration, for example, from 9:00 a.m. to 5:00 p.m. over a three-day duration.

In some embodiments of the invention, rather than using a guest access card issued by the host enterprise, the guest user may use a credit card issued by a credit card vendor such as, for example, Visa, MasterCard, American Express, Discover, etc., to obtain access to network resources through a host enterprise's network. Prior to, during or after attempting to access network resources using a laptop or other user device, the guest user may scan the credit card using a scanner on the host enterprise's premises. Information resulting from the scan may be sent to a network of the credit card enterprise, which may verify the identity of the guest user. The credit card enterprise then may send verification information about the guest user to the host enterprise network, for example, to a guest access management server on the host enterprise network. In response to receiving the verification information, a guest access management server may generate a guest account and guest account credentials, and send the credentials to a device that indicates (e.g., displays) them to the guest user (e.g., as described above). The guest user can then use the credentials to log into the host enterprise network. The guest's access to network resources may be limited and the guest's activity may be monitored and billed, for example, as described above. Further, the duration and specific times of access using the guest account also may be limited.

In some embodiments, rather than using a guest access card or existing credit card, the guest user may use a mobile telephone to obtain access to network resources through a host enterprise's network. Using a mobile telephone scanner provided on the host enterprise's site, the guest user may scan information stored on the guest's mobile telephone, for example, on a subscriber identity module (SIM) card of the mobile telephone. This information may be sent to the guest access management server, which may generate a guest account and guest account credentials in response to receiving the scanned information. The guest account credentials may be sent to a device and indicated (e.g., displayed) to the user, for example, as described above. Using a laptop or other user device, the guest user then may access the network resources through the host enterprise network by entering the guest credentials. Similar to as described above, the guest user's access may be limited to certain network resources, and to a certain duration and specific times within the duration, and the activities of the guest user may be monitored and billed as appropriate.

In some embodiments, a guest user may be provided guest account credentials before arriving at the host enterprise, or a receptionist or another administrator at the guest enterprise may provide the guest account credentials to the guest user upon the guest's arrival. In such embodiments, the guest user may simply log into the network using the guest account credentials without having to first scan a guest card, credit card, mobile telephone or other item.

FIG. 1 is a block diagram illustrating an example of a system 100 for enabling a guest user to access network resources through a host enterprise network, according to some embodiments of the invention. System 100 is merely an illustrative embodiment of a system for enabling a guest user to access network resources through a host enterprise network, and is not intended to limit the scope of the invention. Any of numerous of implementation to such a system, for example, variations of system 100, are possible and are intended to fall within the scope of the invention.

System 100 may include any of: one or more host enterprise user devices (e.g., 102 and 124); one or more guest user devices (e.g., 104); one or more reception user devices (e.g., 105); one or more guest account access devices (e.g., 110); a host enterprise network 106; the Internet 136; one or more guest enterprise networks (e.g., 134); one or more credit card enterprise networks (e.g., 138); and any suitable combination of the foregoing.

As used herein, a “network” is a group of two or more components interconnected by one or more segments of transmission media over which communications may be exchanged between the components. Each segment may be any of a plurality of types of transmission media, including one or more electrical or optical wires or cables made of metal and/or optical fiber, air (e.g., using wireless transmission over carrier waves) or any combination of these transmission media. As used herein, “plurality” means two or more. It should be appreciated that a network may be as simple as two components connected by a single wire, bus, wireless connection, or other type of segment. Further, it should be appreciated that when a network is illustrated in a drawing of this application as being connected to an element in the drawing, the connected element itself is considered part of the network.

As used herein, a “network device” is a device operative to communicate on a network, including, but not limited to: workstations, personal computers, terminals, laptop computers, end stations, user devices, servers, gateways, registers, switches, routers, hubs, bridges, directories, transmitters, receivers, transceivers, wireless access points (APs), repeaters, and any combinations thereof. As used herein, a “user device” is a network device from/to which a user may send/receive communications, and which may serve as an endpoint to communications on a communications network. User devices include, but are not limited to: workstations; personal computers (e.g., PCs); laptop computers, notebook computers; telephones (e.g., landline or mobile); pagers; Blackberry™ brand devices, PCS devices, personal digital assistants (PDAs), smartphones, two-way radios (e.g., “walkie-talkies”), other types of user devices, and any suitable combination of the foregoing.

A network (e.g., any of networks 106, 132, 134, 136 and 138) may be or include any of a variety of types of networks including, but not limited to, a local area network (LAN), a metropolitan area network (MAN), a wide-area network (WAN), a wireless network, a Public Land Mobile Network (PLMN), a Global System for Mobile Communications (GSM) network, a General Packet Radio Service (GPRS) network, a Universal Mobile Telecommunications System (UMTS) network, a Code-Division Multiple Access (CDMA) network, an optical network, a data network, an enterprise-wide network, a wireless personal area network (PAN), a home network, a telecommunications network, a public switched telephone network (PSTN), a broadband network, another type of network, or any suitable combination of the foregoing.

Host enterprise network 106 may include one or more network devices of any of the types described above and may include any of: one or more wireless access points (APs) (e.g., 108), one or more authentication servers (e.g., 120); one or more enterprise user directories (e.g., 122); one or more guest access management servers (e.g., 126); one or more guest user directories (e.g., 128); one or more firewalls (e.g., 130); a host enterprise Intranet (132); other network devices; or any suitable combination of the foregoing.

One or more components of host enterprise network 106 such as, for example, routers, switches and/or combination thereof (not shown) may be configured to define one or more VLANs. One or more of these VLANs (i.e., a guest VLAN) may be defined to include one or more guest access accounts and one or more network resources. The one or more network resources included within a guest VLAN may include the Internet, a guest enterprise network and perhaps one or more network resources residing on host network 106, so that guest users are limited to accessing only these resources. One or more other VLANs may be associated with host enterprise users (e.g., employees and officers). These host enterprise VLANs should be defined to include more resources on host enterprise network 106 than guest VLANs, thus providing enterprise users access to more resources on the enterprise network than guest users, who may be given access to no resources on the enterprise network. For example, the host enterprise VLAN may be configured to include host enterprise Intranet 132.

AP 108 may be configured to provide wireless access to host enterprise network 106 for user devices, including host enterprise user devices (e.g., 102 and 124) and guest user devices (e.g., 104). AP 108 may be configured to pass user credentials received from a user device to authentication server 120. Authentication server 120 may be configured to determine whether the user credentials identify a host enterprise user, for example, by accessing enterprise user directory 122. If the user credentials identify a user as an authorized user of a host enterprise, the user may be given access to resources of host enterprise network 106, according to one or more VLANs to which the user belongs.

If the authentication server 120 determines that user credentials provided by a user device are not those of a host enterprise user, the authentication server 120 may pass the user credentials to guest access management server 126. Alternatively, server 126 may receive the credentials from AP 108 without first going through authentication server 120. Server 126 may determine whether the user credentials identify a guest user, for example, by accessing guest user directory 128. If the user credentials identify the user as a guest user, the guest user may be provided access only to those network resources to which members of the guest VLAN are permitted access.

In some embodiments of the invention, a user device (e.g., any of 102, 104 or 124) may be configured to discover any networks in the vicinity of the user device, for example, by establishing communications with an AP in the vicinity of the user device. For example, a user device may include an operating system (e.g., one of the operating systems available from Microsoft Corporation, specified below) configured to discover networks in its vicinity, e.g., in response to the operating system being launched when the user device is booted (i.e., powered on). If the user device is a host enterprise user device (e.g., 102), then the user device may be permitted to exchange information with host enterprise network 106 based on previous communications exchanged between the user device and an AP. For example, the operating system of the host enterprise user device may automatically provide user credentials previously exchanged between the user device and the AP to establish connectivity.

The AP and/or the guest user device may be configured to recognize when a guest user device has not previously been authenticated. In such cases, the operating system of the guest user device may be configured to prompt the user for guest account credentials (i.e., a guest account ID and a password). The guest user device may only be permitted access to the host enterprise network by providing valid guest user credentials.

In some embodiments of the invention, the user of the guest user device may be provided guest account credentials prior to arriving on the premises of the host enterprise (e.g., by email, paper mail, telephone, etc.), or upon arrival on the premises by a receptionist or other administrator. For example, upon arrival, a receptionist or other administrator may use reception user device 105 to contact guest access management server 106 to obtain guest account credentials.

Obtaining guest account credentials prior to arrival on the enterprise premises may be desirable when a large amount of guest users will be visiting the host enterprise. In such situations, an IT staff or administrator from the host enterprise can use the guest access management server 126 to import information for all of the guests who will be visiting the host enterprise. Such information may include names, job titles, the length of time for which guest access will be necessary, etc. The guest access management server 126 may provide different guest account credentials for each future guest. Upon arrival on the host enterprise premises, each guest user may log onto the host enterprise network 106 through AP 108 or another access point, using the previously provided guest account credentials. The guest access management server 126 then may authenticate each of the guest users, for example, by comparing the user credentials provided with those stored in guest user directory 128.

In some embodiments of the invention, guest users acquire guest user credentials after they arrive on the host enterprise premises, for example, through the use of a guest account access device such as device 110. Device 110 may include any of: user output device 112; guest card scanner 114; credit card scanner 116; mobile telephone scanner 118; other components; and any suitable combination of the foregoing. It should be appreciated that one or more of user output device 112, guest card scanner 114, credit card scanner 116 and mobile telephone scanner 118 may reside on separate guest account access devices, and that one or more of these components may be integrated as a single component.

User output device 112 may include one or more of any type of output device suitable to display information to a user, for example, a monitor, printer or badge-generating device, or to indicate information to the user in some other manner (e.g., through audio), for example, a speaker or telephone. It should be appreciated that user output device 112 is not limited to being part of guest account access device 110, but may be separate and distinct from device 112.

Guest card scanner 114 may be configured to scan a guest card provided by a guest user. A guest card may have guest account credentials, or a value mapping to an account encoded thereon, for example, in clear text or encrypted format. The guest access card may store information on a magnetic strip, a semiconductor memory or on some other form of media. Further, the guest access card may include a transmitter or other means for transmitting/receiving signals and/or information. The guest access card scanner 114 may be configured with one or more components (e.g., heads) to read magnetically-stored information and/or with a receiver or transceiver for receiving information transmitted from a guest card. Further, scanner 114 may be configured to send information scanned from a guest access card to guest access management server 126, for example, across one or more segments of host enterprise network 106.

Credit card scanner 116 may be configured with one or more components (e.g., heads) to scan a credit card and send the scanned information to the appropriate credit card enterprise network (e.g., 138) and/or a component of host enterprise network 106 (e.g., guest access management server 126) configured to send the information along to the credit card enterprise network 138.

In some embodiments of the invention, the host enterprise has a partnership with one or more credit card enterprises. The host enterprise may pay a certain amount of money for each enterprise's validation service. If the host enterprise needs to charge the guest access, a credit card enterprise can charge for access on the credit card.

It should be appreciated that, in some embodiments, scanners 114 and 116 may be integrated as part of a same device, and the same components may be used to read information from guest access cards and credit cards. In such embodiments, the scanning device may be configured to determine from the scanned information (e.g., its format and/or content) whether the card scanned is a credit card or a guest access card, and to proceed accordingly. For example, the scanning device may send the scanned information to the guest access management server 126 if it determines the card scanned is a guest access card, and may send the scanned information to the appropriate credit card vendor otherwise.

Mobile telephone scanner 118 may be configured to read information about a mobile telephone user from a guest user's mobile telephone, for example, from a SIM card of a user's mobile telephone. The mobile telephone scanner 118 may be configured to read this information electromagnetically and/or optically from the mobile telephone, and to send the information about the user to the guest access management server 126.

Guest access management server 126 may be configured to receive: guest account credentials (e.g., a guest account ID and password) in clear text or encrypted form; information corresponding to guest account credentials; information corresponding to a user, other information, or any suitable combination of the foregoing. In response to receiving such information, server 126 may determine guest account credentials and provide them to one or more other network components such as, for example, user output device 112. For example, guest access management server 126 may be configured to receive verification information about a user from credit enterprise network 138, information about a mobile telephone user from mobile telephone scanner 118 and/or guest account credentials for information corresponding to guest account credentials from guest card scanner 114.

Server 126 may be configured to determine guest account credentials included in information it receives (e.g., from guest card scanner 114) and/or create guest account credentials in response to user information or user verification information it receives from mobile telephone scanner 118 and credit card enterprise network 138, respectively. The guest access management server 126 may store guest account credentials in guest user directory 128, and use these credentials to authenticate guest users.

System 100, and components thereof, may be implemented using any of a variety of technologies, including software (e.g., C, C#, C++, Java, or a combination thereof), hardware (e.g., one or more application-specific integrated circuits), firmware (e.g., electrically-programmed memory) or any combination thereof. One or more of the components of system 100 may reside on a single device (e.g., a computer), or one or more components may reside on separate, discrete devices. Further, each component may be distributed across multiple devices, and one or more of the devices may be interconnected.

Further, on each of the one or more devices that include one or more components of system 100, each of the components may reside in one or more locations on the system. For example, different portions of the components of these systems may reside in different areas of memory (e.g., RAM, ROM, disk, etc.) on the device. Each of such one or more devices may include, among other components, a plurality of known components such as one or more processors, a memory system, a disk storage system, one or more network interfaces, and one or more busses or other internal communication links interconnecting the various components. System 100, and components thereof, may be implemented using a computer system such as that described below in relation to FIGS. 6 and 7.

FIG. 2 is a flow chart illustrating an example of a method 200 of enabling a guest user (e.g., a user of guest user device 104) to access network resources through an enterprise network (e.g., network 106), according to some embodiments of the invention. Method 200 is merely an illustrative embodiment of a method of enabling a guest user to access network resources through an enterprise network, and is not intended to limit the scope of the invention. Any of numerous other implementations of such a method, for example, variations of method 200, are possible and are intended to fall within the scope of the invention.

In Act 202, a guest user arrives at the premises of an enterprise, for example, in the reception area or a lobby of the enterprise offices. In Act 204, the user may acquire one or more guest account credentials, for example, as described below in relation to FIGS. 3-5. It should be appreciated that, in some embodiments, the guest account credentials may be acquired before the guest user arrives on the premises of the host enterprise, as described above.

In Act 206, the guest user may provide the guest account credentials to an enterprise network. For example, the guest user may enter the guest account credentials through a user device (e.g., device 105), for example, in response to prompts. These guest account credentials may be passed to an authentication component of the network such as, for example, guest access management server 126.

In Act 208, the enterprise network may provide the guest user access to network resources through the enterprise network based on the guest account credentials. For example, the guest account credentials may be passed to the guest access management server 126, which may verify the credentials using guest user directory 128. If the guest account credentials are authenticated, the guest may be provided access to network resources such as, for example, the Internet 136, the guest enterprise network 134, and perhaps resources on host enterprise network 106 itself. Access to these network resources may be regulated using VLAN technologies. That is, one or more VLANs may be defined that include the Internet and the guest enterprise network, a limited amount of resources of network 106, and/or one or more guest accounts. One or more components on host enterprise network 106 (e.g., routers, switches, or suitable combinations thereof) may be configured to control access to network resources defined for one or more such VLANs based on the guest account ID provided by a guest user. Other technologies may be used to regulate guest user access.

In Act 210, the host enterprise network may monitor activities of the guest user, for example, the network resources that it accesses and/or with which it exchanges communications. In Act 212, the host enterprise network may bill the guest user for certain activities, for example, accessing particular network resources such as, for example, Internet.

The guest account provided for the guest user may be configured to be of limited duration and for use only during specific times during this duration. For example, the user account may be configured to be for use during a three day period (e.g., Monday-Wednesday) only during business hours, e.g., 9:00 am-5:00 pm. Accordingly, the guest management access server and the network components responsible for routing traffic on the host enterprise network may be configured to deny access to the guest user when the duration of the guest account expires and when the guest user attempts to access network resources outside of the specific times designated for guest access. The guest access management server and these other components may be configured to do so based on the guest account credentials provided by the guest user when logging in and/or when transmitting packets on the guest enterprise network.
